Blocking IPv6 through the EoIP tunnel

Hi!
How to disable ipv6 advertise through the EoIP tunnel?
In the bridge settings, where the EoIP tunnel was added, I successfully blocked DHCPv4 (drop udp on 67-68), but I can not understand how to block the IPv6.
Please, help.

IPv6 using neighbor discovery protocol, so just disable it on EoIP interface or on hardware interface into lan.

which ports use NDP?

It’s ICMPv6 protocol. Number 58 on IPv6 layer. Like OSPF protocol is number 89 on IP layer.

what do you want to pass through the tunnel? probably it is easier to block stuff using ethertype filtering.
